Introduction Our People and Culture Environmental Health 13 2021 Sustainability Report A Modern, High-Performing Health System Responsible Business Practices Performance Data Sustainability governance UnitedHealth Group has a long- standing commitment to sustainability supported by our senior leaders and Board of Directors. As part of its ongoing oversight, the board reviewed committee charters and made several changes in 2021, including assigning oversight for the company’s environmental, social and governance (ESG) agenda to the Governance Committee and having other committees oversee specific ESG elements within their purview. The Governance Committee is responsible for providing oversight of ESG policies and practices, including identifying key ESG topics, ensuring appropriate board or committee oversight of those topics, overseeing the company’s environmental and climate change initiatives and corporate citizenship activities, and reviewing the company’s ESG sustainability reports. The Audit and Finance Committee oversees management’s processes to identify ESG investment criteria and to ensure the accuracy of key disclosures related to ESG matters. The committee also oversees our Compliance and Ethics program. The Compensation and Human Resources Committee reviews the company’s strategies, programs and outcomes related to human capital management, as well as diversity, equity and inclusion. We reconstituted our Public Policy Committee, now renamed the Health and Clinical Practice Policies Committee, to better reflect its expanded oversight of clinical care and practice matters and access to care, in addition to health policy matters. The Health and Clinical Practice Policies Committee oversees management’s efforts and initiatives to expand access to health care; improve health care affordability; advance clinical care and safety; enhance the health care experience; achieve better health outcomes; advance health equity; and reduce health disparities. To support our growing focus on sustainability, the company created the role of chief sustainability officer, responsible for developing and implementing a comprehensive ESG strategy; establishing annual and long- term sustainability goals, performance metrics and a governance structure to achieve them; and helping to shape our ESG agenda. The chief sustainability officer, appointed in 2022, is assisted in overseeing our day-to-day sustainability agenda through close partnerships with a wide range of leaders across Optum, UnitedHealthcare, Operations and Facilities Management, Sourcing and Procurement, Clinical, Human Capital, Finance, Compliance and Privacy, Legal and Risk Management, Compliance and Regulatory Affairs, Communications, and Enterprise Resiliency and Response. Additionally, in 2022, we plan to establish a cross-enterprise steering committee composed of senior- level leaders and key internal stakeholders who will be responsible for collaborating and executing on all aspects of the enterprise ESG strategy.
